I brought this product with the impression that a heart rate strap will not be needed to measure my heart rate when exercising. When the product arrived I realized I purchased a product that has that is a computer that tracts all your work outs and file the results.

I don't need all that as I was only interested in seeing my heart when exercising and calories burned. This product would suit a professional athlete who participate in competition. But for the average exerciser who works out three to maybe 4 days a week the product is over kill and expensive.
